Full Description
Kinetic View of Dynamic Plasticity and Fracture of Polycrystalline Solids offers a comprehensive exploration of kinetic models designed to enhance simulations of diverse mechanical processes. Covering topics such as dislocation plasticity, deformation twinning, phase transitions, dynamic recrystallization, pore growth, and multiple cracking, the book is structured into three main sections. The opening part presents a state-of-the-art review of kinetic structural models for plasticity and fracture, establishing a solid theoretical foundation. The second section introduces innovative, fully discrete kinetic model formulations, where variables are defined on polytopal cell complexes rather than traditional continuous manifolds, advancing the modeling approach.
The third section delves into the practical implications of these formulations, including new mechanical criteria for plasticity and fracture and corresponding rheological models relevant to high-strain-rate material deformation. Additionally, the book discusses finite element method-based simulation outcomes and offers practical guidance for modeling deformation in nano-sized samples that naturally experience high strain rates. It also provides valuable advice on leveraging microstructural characterization data, such as that obtained from SEM or X-ray techniques, to inform and refine modeling efforts.
